What is the monomer of a protein?
Amino Acid
What is the function of the ribosome?
Make proteins!
If a mutation occurs in a cells DNA, this cell can eventually divide uncontrollably. What do we call this when this happens?
Cancer
What is the shape of DNA called?
Double helix
Define and an example of an abiotic and biotic factor.
Abiotic = nonliving (ex. water, rocks, sunlight, etc.)
What do we call the variable in an experiment is observed and measured?
What type of cell is complex, has a nucleus, and membrane bound organelles?
Translate the following DNA into mRNA:
TAC - CTA - CGA
AUG - GAU - GCU
A white chicken and a black chicken mate and produce a spotted chicken. What type of complex inheritance is this an example of?
Describe the difference between a food web and a food chain.
food chain - one pathway that energy can flow
food web - multiple pathways that energy can flow
You are sitting in class and all of a sudden your stomach growls. This is a sign that you are hungry. This is your bodies way of maintaining what characteristic of life?
Metabolism or homeostasis
Write out the equation for cellular respiration. Label the products and reactants.
C6H12O6 + O2 --> H2O + ATP + CO2
glucose + oxygen --> water + energy + carbon dioxide
Original DNA: TAC - CCG - TCG
Mutation DNA: TAA - CCC - GTC - G
What type of mutation occurred?
Insertion
The gene for a long tail in dogs is dominant over short tails. If two homozygous dominant dogs mate and have 4 puppies, how many would you expect to have long tails?
All 4
What is the approximate carrying capacity based on this graph?
2,000
There are three properties of water that we learned about at the beginning of the semester. What property is being displayed in this picture?
Adhesion
Osmosis is the movement of water across a semi-permeable membrane. If there is a higher concentration of water outside of the cell compared to inside, what direction will the water move? What type of solution is this called?
Water will move inside the cell.
Hypotonic solution
What is the different between tRNA and mRNA? What process is each involved in and which one has an anticodon vs codon?
mRNA - made during transcription, has codon
tRNA - carries amino acid to ribosome during translation, has anitcodon
Are males or females more likely to inherit a genetic disorder such as colorblindness that is inherited on the X chromosome?
Males because they only have 1 x chromosome.
Striped hyenas have been see hunting alongside grey wolves. The wolves have excellent hunting skills, and the hyenas can break bones into smaller pieces. What symbiotic relationship is this?
Mutualism
Name all 3 parts of cell theory.
1. Cells come other cells
2. Cells are the basic unit of organization
3. Cells are smallest living thing.
Meiosis is a reduction division where a cell goes from 46 to 23 chromosomes. What process is occurring in this picture? (hint: it takes place during prophase I).
Crossing over
Amino acid sequence for hair type:
Straight hair: His - Pro - Ala
Wavy hair: Ser - Pro - Iso
Curly hair: Ser - Val - Iso
A person has the following DNA sequence:
TCA - GGG - TAA
Use the protein sequence above to determine what the person's hair type will be.
Wavy hair
This pedigree shows a recessive disorder. Anyone who is shaded in has the trait of interest. If person 3 & 4 in generation II have another child, what is the chance that the child will have the recessive trait?
1/4 or 25%
Why does energy decrease as you move up an energy pyramid?
Only 10% of energy transferred, the other 90% is lost as heat.
